Patented Mar. 29, 1921 A conduit 12 extends axially through the body 11 and projects into the end section 3 within which it is provided with an enlargement 12 the exterior of which is of the same form but smaller than the chamber in the end or head 3. Said conduit is held in engagement with the body 11-by a coupling sleeve 13 that is screwed thereon and into the end of said body. Said sleeve is or" such length that it extends to the end Wall of the section 2 and is* also fitted on the end of a conduit 14 by which the iluid to be compressed is supplied to the chamber within the cap or end section 2. A collar 15 is lscrewed into a socket at the lower end of body 11, about the conduit 12, said collar having a lurality of inwardly projecting radial stu s or pins that contact with the conduit and assist in maintaining it in thev desired relation to the body 11.

' The supply conduit 14 through which the fluid to be compressed is supplie to the apparatus commu'nicates with the chamber in the end section 2 adjacent the inlet end of the passage 10 through a plurality of radially extending ducts 16. A series of longitudinally extending duets 17 in the body of the coupling sleeve 13 connect the passage sur-k rounding the conduit 12 with the interior of the tubular extension of the end member 2 to rovide a passage for the compressed fluid rom the space surrounding the conduit 12 which communicates with the chamber in the head or end section 3.

18, 19 designate, respectively, flexible pipes or tubes for supplying fluid to be compressed to the conduit 14 and for the escape of compressed .fluid from the space surrounding said conduit.

' A body 20 of suitable liquid, for example mercur is introduced into the chamber in the en or head 2 and as the shaft 4 is revolved separate masses of such liquid will under the action of centrifugal foree'successively enter the' passage 10 and act to compress the intermediate bodies of fluid received therein from the chamber about the coupling sleeve 13. The compressed fluid and mercury will be separated in the space surrounding the enlargement on the end of the conduit 12 the mercury being forced back through said tube, against the lcentrifugal force, by the pressure generated, until it reaches the ducts 16 through which it passes into the chamber surrounding the coupling sleeve 13 thus completing its circuit. The compressed 'fluid passes through the space surrounding the conduit 12 and the ducts 17 into the tubular extension of the end section 2 and to the pipe19.

As heretofore stated the improvements are particularly adapted foruse with refrigeration apparatus and for such purpose the conduits 18, 19, are connected with a suitable expansion Valve and evaporation chamber whereby the compressed fluid is caused to extract heat from a circulating body of brine or air, for example, as it passes from one of said conduits to the other. The heat thus extracted is' given off by the compressed fluid upon its condensation in a suitable chamber, or this may be accomplished by adding sufficient radiating surface to the compressor itself.

In the embodiment ot the invention for this purpose illustrated in Fig. 2 the extension of the compressor head 2 connnunicaies with a suitable evaporationl chamber 2l which is arranged within a tank or receptacle 22 surrounded by walls of insulating material.

The `connection between the compressor and evaporation chamber is shown as comprising two sections 24, 25. Between the adjacent ends of said sections, and collars 23, 23, thereon, is clampedva member 26 in 'which the end of the conduit -14 is secured.

A conduit 27 extends through the member 26 and connects the passage for compressed fluid surrounding the conduit 14 with the interior valve chamber `of the evaporation chamber 21. As shown in Fig. 3 the outlet from the valve chamber 23 to the main evaporation chamber 21 is controlled by an expansion valve having a bellows shaped body 29;

In this arrangement the parts are supported by and connected with the shaft 4 by tavo counterbalanced arms 5, 31, a universal joint or ball 30 being provided in the insulating wall, the ball 30 is disposed in a rotatable bushing 30 and the shaft 4, at that portion which passes into the receptacle is oiiset from its axis of rotation and the oflset portion 4h passes through the bushing 30 causing it to rotate with the shaft.

A suitable refrigerant fluid may be caused to circulate through the tank 22 and pipes 32, 33 connected therewith, or said pipes may serve merely to conduct air to and from the tank.

Means are also provided for imparting rotary motion to the peripheral groored body 11 relative to the liquid in the casing in which it is arranged, said means. as shown, comprising a stationary band wheel 34 mounted coaxial with the shaft 4 and connected by an endless belt 35 with a pulley or wheel 36 onthe outer end of the stem of the body 11 in which stem the conduit for conducting fluid to be compressed to the compressor is provided.

By thus rotating the compressor on its own axis as well as about the axis of shaft 4 a definite volume of fluid will be compressed in a given time. lt will be seen that if the pulleys 34 and 36 are of the same size. the resulting motion given to the compressor elements will be the same as in the type of apparatus illustrated in Fig. 1.

After the apparatus has been con- Structed and properly filled with the required materials at the factory, it can be permanently sea-led` and requires no consideration or attention by the user. A Very small motor is required to operatel it and in the preferred form, illustrated in Figs. 6 to 12, this serves as a counterbalance to the com ressor to insure smooth rotation thereof. he apparatus is charged with sufficient mercury, so that when operating, there is always mercury present in the chamber 43, and as long as this mercury is present, it will enter the helical passage and be forced through said passage, by the movement ot the helix about the axis of the shaft 4, into the chamber 44. The amount of mercury vpresent is suiiicie'nt to #insure illing the tube 45, and'to insuresudicient mercury in the chamber 43 to feed the helical groove and in chamber 44,-t0 seal the lower opening of the tube 45, and to provide for the proper amount ot mercury -in the helical tube. When the device is at rest, mercury is present in the annular passage surrounding the tube 45, but upon rotation, the luid under pressure is forced into the chamber 44 and this iiuid enters the annular passage 'and rises up through the mercury and forces the mercury therefrom into the chamber 44. With the devi rotating about the shaft 4, the mercury must pass through the helical tube. The passage of this mercury builds up apneumatic pressure or vapor pressure in the chamber 44 which pressureis exerted on the mercury in chamber 44, causing the mercury to move up the tube 45. The movement of the mercu through the tube 45 is A due t0 two causes, rst, the presence of sufthat when the apparatus is subsequentlyI stopped, mercury' will remain in the chamficient mercury to cause a back "flow, and

second, the pneumatic pressure produced in the chamber 44. Sufiiclent mercury is containedin the apparatus to insure the pres- .enee of mercuryin the chamber 43, when the apparatus is at rest. When the apparatus is started for the first time, the mercury is introduced into the low pressure chamber .43 in suliicient amount to insure the subs -uent proper operation of the apparatus. is amountof mercury 1s such bei' to insure .proper subseduent starting.

Leraars 'the apparatus is at rest, to partially lill the convolutions ot the helical tube with spaced plugs of mercury, to fill the tube 45 and the chamber 44 and the passage surrounding the tube 45 and to leave sufiicicnt mercury in the chamber 43, to insure the subsequent operation of the apparatus.
